Split Array at Repeating Object in Array - php

Question

I am parsing an XML file and creating two arrays: one of the XML tags ($tags), and the other as the values for the tags ($values). As it parses, it adds the tags and values as it goes, when it's done, I implode the arrays and put them into a MySQL statement:
$sql = "INSERT INTO everything ($tags) VALUE ($values)";
This works fine until I have repeating tags, and then the SQL statement doesn't work....
Is there a way to find the first repeated word in the $tags array and split it at that word (Keeping the tags that follow it) and also split the $values array at the same index that $tags was split, so that the information stays in the same order?
So ultimately converting something like this:
INSERT INTO everything (AmazonOrderID,MerchantOrderID,ShipmentID,MerchantFulfillmentID,PostedDate,AmazonOrderItemCode,SKU,Quantity,Principal,Commission,AmazonOrderItemCode,SKU,Quantity,Principal,Commission,AmazonOrderItemCode,SKU,Quantity,Principal,Commission,FBA) VALUE ('1','1','D','A','2015','64','OX','1','18','-2','64','WA','1','23','-2','29','WAG','1','49','77','97');
Into something like:
INSERT INTO everything (AmazonOrderID,MerchantOrderID,ShipmentID,MerchantFulfillmentID,PostedDate,AmazonOrderItemCode,SKU,Quantity,Principal,Commission) VALUES ('1','1','D','A','2015','64','OX','1','18','-2');
INSERT INTO everything (AmazonOrderItemCode,SKU,Quantity,Principal,Commission) VALUES ('64','WA','1','23','-2');
INSERT INTO everything (AmazonOrderItemCode,SKU,Quantity,Principal,Commission,FBA) VALUES ('29','WAG','1','49','77','97');
Thanks in advance!...

I just base from your "something like".. :)
$fields = ['AmazonOrderID', 'MerchantOrderID', 'ShipmentID', 'MerchantFulfillmentID', 'PostedDate', 'AmazonOrderItemCode', 'SKU', 'Quantity', 'Principal', 'Commission', 'AmazonOrderItemCode', 'SKU', 'Quantity', 'Principal', 'Commission', 'AmazonOrderItemCode', 'SKU', 'Quantity', 'Principal', 'Commission', 'FBA'];
$values = ['1','1','D','A','2015','64','OX','1','18','-2','64','WA','1','23','-2','29','WAG','1','49','77','97'];
// i just added this to avoid error produced by: `Undefined offset` error warning
error_reporting(0);
$fields_dup = array();
$values_dup = array();
for ($i = 0, $j = 0; $i < count($fields); $i++)
{
if (in_array($fields[$i], $fields_dup[$j]))
$j++;
$fields_dup[$j][] = $fields[$i];
$values_dup[$j][] = $values[$i];
// or maybe you want to add ` and ' make your statement look like:
// INSERT INTO table (`field1`, `field2`) VALUES ('value1', 'value2')
//
// $fields_dup[$j][] = "`".$fields[$i]."`";
// $values_dup[$j][] = "'".$values[$i]."'";
}
error_reporting(E_ALL);
// just to show what is produced
var_dump($fields_dup);
var_dump($values_dup);
// while you can also construct your statement in a loop like
for ($i = 0; $i < count($fields_dup); $i++)
{
$sql_fields = implode(',', $fields_dup[$i]);
$sql_values = implode(',', $values_dup[$i]);
echo "INSERT INTO everything ($sql_fields) VALUES ($sql_values) <br>";
}
Output would be:
//var_dump($fields_dup);
array (size=3)

4 => string '77' (length=2)
5 => string '97' (length=2)
// for the last for-statement
INSERT INTO everything (AmazonOrderID,MerchantOrderID,ShipmentID,MerchantFulfillmentID,PostedDate,AmazonOrderItemCode,SKU,Quantity,Principal,Commission) VALUES (1,1,D,A,2015,64,OX,1,18,-2)
INSERT INTO everything (AmazonOrderItemCode,SKU,Quantity,Principal,Commission) VALUES (64,WA,1,23,-2)
INSERT INTO everything (AmazonOrderItemCode,SKU,Quantity,Principal,Commission,FBA) VALUES (29,WAG,1,49,77,97)
Is that what you are trying to do?
Hope this is helpful, Cheers! ;)
